On the headset, do you need the 'walkie-talkie' as well? cuz the cord between both would most like need some kind of rigging. I could make the headset pretty easily tho.

As for a laptop, I have one in my freebies, it needs scaled and stuff, as I mad it at the beginning of my modeling career and didn't know what all I was doing. I'm pretty sure there's another free one also you can check out.

If you google most of that stuff, I bet a lot will show up, just add 'free 3D model' to your search string and it'll help out.

Here's on kind of headset in the freebies here:

There's also a fire extinguisher at Daz:

...and it's cheaper than the one at the 'squid' lol

But if you do a little more searching than I have, you may find more.
